    Study Notes

    Cell Structure

    • Plasma membrane: semi-permeable membrane that separates the cell from its environment
    • Cytoplasm: jelly-like substance inside the cell membrane, where metabolic processes take place
    • Nucleus: control center of the cell, contains genetic material (DNA)
    • Mitochondria: energy-producing organelles, responsible for cellular respiration
    • Endoplasmic reticulum: network of membranous tubules and cisternae, involved in protein synthesis and transport
    • Ribosomes: small organelles, site of protein synthesis
    • Lysosomes: membrane-bound sacs, contain digestive enzymes for breaking down and recycling cellular waste
    • Golgi apparatus: complex of flattened sacs, involved in protein modification and secretion

    Cell Functions

    • Metabolism: conversion of energy and nutrients into usable forms
    • Growth and development: increase in cell size and number, differentiation into specialized cells
    • Response to stimuli: ability to react to changes in environment, e.g. light, temperature, touch
    • Reproduction: creation of new cells through cell division (mitosis or meiosis)
    • Cell signaling: communication between cells, through chemical signals (hormones, neurotransmitters)

    Cell Types

    • Prokaryotic cells: lack nucleus, typically small and simple, e.g. bacteria
    • Eukaryotic cells: have nucleus, typically larger and more complex, e.g. plants, animals, fungi
    • Stem cells: undifferentiated cells, capable of differentiating into various cell types

    Cell Division

    • Mitosis: division of somatic cells, results in two identical daughter cells
    • Meiosis: division of reproductive cells, results in four non-identical daughter cells with half the number of chromosomes as the parent cell
